Description
Technical field
The invention belongs to fiber preparation field, it is related to a kind of elastic force and imitates linen-cotton polyester fiber and preparation method thereof.
Background technique
Polyethylene terephthalate (PET) fiber since the advent of the world, obtains fast because of the excellent performance that it has
Suddenly develop, yield has become the hat of world's synthetic fibers.Polyester fiber has breaking strength height, elasticity modulus height, returns
Elasticity is moderate, thermal finalization is had excellent performance, heat-resisting light resistance is good and a series of excellent performance such as acid-fast alkali-proof good corrosion resistance,
And fabric prepared therefrom has many advantages, such as that crease-resistant and stiffness is good, so, polyester fiber is standby to be widely used in clothes and family
The fields such as spinning.
As the development of modern textile technology and people's living standard are continuously improved, people are to taking, decorate and industrial
Yield, performance and the quality of chemical fibre used by textile are put forward higher requirements, and therefore, in recent years, researcher causes
Power is in the research and development of the new varieties of chemical fibre, to meet people to the market demand of the fiber with high added value.Abnormity
Fiber is that have special cross-section shape and function made of spinning melt spins after the spinneret orifice with certain geometrical shape squeezes out
The chemical fibre of energy.The cross sectional shape of fiber affects the performance of yarn and fabric, utilizes the spray with different shape and size
The composite spinneret of wire hole can spin out the profiled filament with different cross section shape, and the material and shape feature of fiber influence
The arrangement of the performance of fiber, fiber and fiber in the yarn influences the performance of yarn, the arrangement shadow of yarn and yarn in the fabric
The performance of fabric is rung, thus the shape feature of fiber is the essence for influencing yarn and fabric property.
The improvement that fiber with different cross section shape plays yarn and fabric is different, profiled filament
Also there is also some difficulties and deficiencies for class textile research aspect, in recent years, with the double profiled filaments of plate or with the more double abnormity fibres of plate
Dimension is the advantages of solving the existing insufficient important means of profiled filament, can integrate two kinds of profiled filaments, to meet people to different
The demand of shape fiber-like textile high quality and functional diversities.Although however researcher is to the double profiled filaments of same plate or same plate
More double profiled filaments have carried out a large amount of research, but in actual production with the double profiled filaments of plate or with the more double profiled filaments of plate
It is difficult.It is viscoelastic fluid since polyester fondant is non-newtonian fluid, while making stickiness flowing in spinneret orifice,
Elastic deformation will occur, form certain pressure, therefore, polyester fondant can generate certain pressure drop, spinneret after going out spinneret orifice
Shape, size, length and the mutual relationship in hole can all have a huge impact its pressure drop, existing research one
As only take into account spinneret orifice shape it is identical or cross-sectional area is equal, and shape, size and the mutual influence of length
Without reference to the pressure drop that will result in when polyester fondant is flowed out from the spinneret orifice of different shapes of same spinneret in this way is different
Cause so that there is difference in the extruded velocity between the different fiber in section, therefore polyester fiber will appear that fiber number is irregular, intensity not
Phenomena such as uniform uneven dyeing, influences going on smoothly for fibre spinning processing.
The penetrability of existing polyester fiber is poor, and the fabric comfort being made from it is poor, but penetrability is good natural
Ramie cotton fabric, which is easy corrugation, to be influenced beautiful and is not easy to arrange.Cross profiled filament and circular fiber can be solved now with plate extrusion
This problem for having technologic material penetrability and wrinkle resistance cannot be considered in terms of, this is imitated using the wicking that cross profiled filament generates
It answers, it is again not wrinkled while keeping fabric good with penetrability to be easy to arrange, therefore realize that with the double profiled filaments of plate be to solve
The key of this problem.
Therefore, how to overcome the prior art to cannot be considered in terms of the defect of penetrability and wrinkle resistance, prepare one kind and take into account moisture-inhibiting
Property and wrinkle resistance PET fiber become current urgent problem to be solved.
